McMaster Carr

I get a lot of small stuff from them, I have an old catalog that's about 5" thick. I have saved a lot even on small things.

Set screws for my goodson valve seat tooling, I can get a 10 pack cheaper from McMaster than goodson wants for 1.

The way things have been going this year, I really was surprised at how quick my stuff came.

Their shipping price was actually less than expected. All in all a win/win.
